PSG are still totally dominant but not as clinical as they were in the first half. A corner is cleared. I'm going to stand down my record score chat for now.

Luis Suarez hasn't scored an away Champions League goal since September 2015. Unless it's Lionel Messi, I just don't see Barcelona scoring.

If Spurs can stop Barcelona building from the back then they'll definitely be able to get something out this game.

A panic for Red Star keeper Milan Borjan. Marco Verratti lifts a ball over the top and the keeper can't work out if Edinson Cavani is going to get it so he turns it out for a corner - but it could have gone anywhere.

The last time I saw the Wembley pitch this bad, Steve McClaren was stood on the side with a brolly in his hand!

Kylian Mbappe has a lob saved by the keeper now - that's 19 shots, and 13 on target for PSG.

Milan Borjan is having a great game in goal despite conceding four.

Schalke make their second change as Spurs legend Nabil Bentaleb replaces Sebastian Rudy.

Should Daniel Sturridge be starting?

Stephen: Surprised to see the same front three for Liverpool. Had a feeling he would give Sturridge a run out and rest one of the red arrows for Sunday's game.

Kahn: What does Sturridge need to do to start the match? Clearly better than Firmino at the moment, better than even Salah on form. Keita should have played at the weekend too, good to see him back.

8-0 is the answer for biggest Champions League wins - Liverpool against Besiktas last year and Real Madrid v Malmo in 2015.

There have been 10 7-0s.

PSG are absolutely running riot here - more skills from Kylian Mbappe who finds Neymar and his lob is saved.

Second earlier, Neymar had another chance stopped.

I might need to check what the biggest ever Champions League win is.

Gerard Pique becomes the 36th player to make 100 Champions League appearances.

Can you name the other 35? Take the quiz here.

(I got 30.)

Tottenham are without a host of first-team players but are boosted by the return of captain Hugo Lloris.

The goalkeeper comes in for his first game since August.

Christian Eriksen, Dele Alli, Jan Vertonghen and Mousa Dembele are all injured.

Ben Davies, Victor Wanyama, Harry Winks and Erik Lamela are the other players to come in from the win at Huddersfield on Saturday. Eric Dier is dropped to the bench.

Spurs XI: Lloris, Trippier, Alderweireld, Sanchez, Davies, Wanyama, Winks, Lamela, Lucas, Son, Kane.

Subs: Gazzaniga, Rose, Dier, Walker-Peters, Skipp, Sissoko, Llorente

Most of Barcelona's big guns start with Lionel Messi, Luis Suarez and Philippe Coutinho up front.

Forward Ousmane Dembele only makes the bench however - as Arthur gets a start in midfield.

Centre-back Samuel Umtiti is suspended so Clement Lenglet comes in.

Barcelona XI: Ter Stegen, N Semedo, Pique, Lenglet, Jordi Alba, Arthur, Busquets, Rakitic, Coutinho, Suarez, Messi

Subs: Cillessen, Denis Suarez, Dembele, Rafinha, El Haddadi, Vidal, Vermaelen

Kylian Mbappe has a chance to make it five - stopped by the legs of keeper Milan Borjan.

Schalke also make a switch at the break - as Suat Serdar replaced the booked Omar Mascarell.

Under way in Paris - and in Moscow.

Red Star make two changes at the break - not surprising. Defender Srdjan Babic and striker Milan Pavkov are on.

The last time Liverpool visited the Stadio San Paolo, back in October 2010, they came away with a forgettable goalless draw in their third Europa League group-stage tie.

They had won just one of their opening eight fixtures in the Premier League, and went into the game on the back of a 2-0 Merseyside derby defeat at Goodison Park.

They were 19th in the table under Roy Hodgson and the squad they named that day didn't include Steven Gerrard and Fernando Torres.

They have come a long way since then...

Liverpool XI that day: Reina, Kelly, Carragher (C), Skrtel, Konchesky, Poulsen, Spearing, Shelvey, Jovanovic, Babel, N'Gog.
